AI Technical Summary

Technical Problem

In existing technologies, the driving device for the finger mechanism is located on the palm, which occupies the space of the palm and affects the overall sensing ability of the robotic hand.

Method used

The first and second phalanx drivers are placed in the receiving cavity of the first phalanx of the finger mechanism. The housing is used as a transmission link to reduce the space occupied by the palm. The finger mechanism is driven by a push rod to achieve bending and rotation movements.

Benefits of technology

It saves space in the palm, increases the space for component placement within the palm, enhances the multimodal perception capability of the robotic hand, improves the flexibility and transmission efficiency of the finger mechanism, reduces frictional loss, and enhances the stability and load-bearing capacity of the system.

Abstract

This application discloses a finger mechanism, a robotic hand, and a robot. The finger mechanism includes: a base for connecting to the palm; a knuckle assembly connected to the base, the knuckle assembly including a first knuckle and a second knuckle rotatably connected in sequence; a first knuckle driver located in a first receiving cavity, the first knuckle driver being mounted on the base, the output end of the first knuckle driver being connected to the first knuckle, the first knuckle driver being used to drive the first knuckle to rotate; and a second knuckle driver located in the first receiving cavity, the second knuckle driver being mounted on the first knuckle, the output end of the second knuckle driver being connected to the second knuckle, the second knuckle driver being used to drive the second knuckle to rotate around the first knuckle. This application can save space in the palm, thereby allowing more components (such as sensors) to be arranged within the palm, thus improving the effective use of space within the palm and increasing the multimodal sensing capability of the robotic hand.
